Friendly with neighbours

Hi
This is my 1st story and i wanted to let everyone know what happed to me
I am married to Jeff and he works for the mines in Western Australia and only comes home every 3 weeks.
We have no children and i stay home alone while he is away. I do some part time work but it is not much. We are in our late 30's and it is o/k. While at home alone i get horny and most of the time i am naked. Every night i please myself at least 2 times. When i hang out the washing of a morning i do it naked, it feels so good. When i bring the washing in i also am naked.
I had a couple move in next door, they are Asian, nice couple and they are 31 and 33. Her name is Kim and his name is Tim. I was bring in the washing one afternoon when i heard them in there pool. I was a bit taken back thinking they may have seen me. I was a bit horny so i took the washing off and then decided to go over to the fence to see if i could see them and i was taken back. They were both naked. They were both clean shaven and his cock was about 6inched on the slack. As i watched i saw Kim suck his cock, then jerk him off. I went back inside and pleased myself. It was the 1st time i had seen another couple having sex, it was such a turn on.
Jeff came home the next weekend so i had to behave but our sex life was great. The next weekend Jeff had to go back to work and i would not see him for 3 weeks.
On the Tuesday i saw Kim out the front of her house collecting the mail. We chatted for a while and she told me Tim would work from the office 2 weeks and then work from home 1 week. She then asked me if i would like to have a swim anytime i was welcome to join her or both of them. As it was worm weather i joined her a few times the next couple of weeks. When i went for a swim i wore a tight, brief one piece and Kim wore a two piece brief swimmers. When it was the Friday before Tim was to work from home Kim said she wanted to ask me something. I looked at her and she asked me - do i like watching them over the fence. I was dumfounded and then said i did. She then told me Tim does not know i watch so don't tell him. She then told me they had talked about being naked with other people but he said he would be uncomfortable.
After we talked Kim asked if i would like to be naked with her and as she asked she stripped off. I was a bit worried at 1st but i stood up and stripped off. After a swim i got out, got dressed and went home. I told Kim i would think about it.
I had never been naked with anyone except Jeff but it turned me on. When i got home i stripped off and pleased myself. I had a lot to think about.. Jeff was home the weekend so i had to be careful but our time together was great and the sex was even better that weekend. All i thought about was what Kim had asked me. I saw Kim on the Monday morning and she asked if i had given any thought about what she had asked me and i said i had. Kim then told me she had talked to Tim and he said he would try as they had never been naked with anyone else. I told her i would try and hope it would be o/k.
The next week Tim was working from home. I told Kim i would come over on the Tuesday for a swim. I was so turned on leading up to the day I pleased myself just before going over for a swim. We sat around the pool, had some drinks and chatted. We had our swimmers on and Tim asked if we wanted another drink and we both said o/k. When Tim went to get the drinks Kim asked if i would get naked with her and she said Tim will come back naked so i said o/k, i was so horny. We stripped off and sat back down. Kim shocked me when she said i could touch Tim's cock if i want. When Tim came back out he was naked and his cock was a bit hard. He gave Kim her drink and then came over to me, he stood next to me and handed me my drink. As i reached for if my hand brushed his cock, he moved back a bit and i grabbed his cock to stop him. I saw him look at Kim and she smiled at him so i started jerking his cock. After a bit i sat on the side of the chair looked at Kim and put his cock i my mouth. As i sucked his cock i saw Kim move over next to Tim and kiss him. As i was sucking him a saw Kim next to him and her pussy was at my eye height . It was not long and Tim said he was going to cum so i took it out of my mouth and jerked him off. When it was over we went inside and talked about what had happened. Kim was excited and asked if we could do it again sometime and Tim said he was ok as well. I also said i we ok. When it was time to leave Tim gave me a cuddle and i felt his cock between my legs and it felt great and then Kim gave me a cuddle and she touched my tit and then fingered my pussy. I was so horny i left and went home. I pleased myself 3 times and thought about what i had done. It was so great.
